In order to extend the service life of diesel generator sets, Haixing reminds users to pay special attention to the maintenance work of diesel generator sets in winter. Only by paying attention to the impact of cold climate on the generator set during daily use in winter can the diesel generator set be protected from damage. 1: Avoid choosing fuel at will. The low temperature in winter makes the fluidity of diesel worse, the viscosity increases, and it is not easy to dissipate, resulting in poor atomization, deterioration of combustion, and deterioration of the power and economic performance of the diesel engine. Therefore, light diesel should be used in winter with low cooldown points and good ignition performance. It is generally required that the defrost point of the diesel engine should be 7-10℃ lower than the local minimum temperature in the current season. 2: Use open flame to help ignite. The air filter cannot be removed, and then ignite it with cotton yarn dipped in diesel, and then made into a ignition object and placed in the intake pipe to assist in the combustion start. In this way, during the startup process, the dust-containing air from the outside will be directly sucked into the cylinder without filtering, causing abnormal wear of pistons, cylinders and other parts, and also causing

Among the fuel injection systems that have the most significant improvement in combustion effects, 'high-pressure injection' and 'injection freedom' have become important means in current fuel injection systems.The common rail injection system has entered the second generation, and can achieve an injection pressure of 160-180MPa and five multi-stage injections within the variable range of the injection period above 180°C.In the future, through measures such as improving the strength of each part of the common rail injection system and reducing oil leakage, it is expected to achieve high-pressure injection above 200MPa.In the future, there are methods to improve combustion such as premixed combustion and low NOx combustion. In order to achieve premixed combustion, measures such as multi-stage injection and switching combustion methods that can promote premixing are adopted, which requires a higher degree of injection freedom.In addition, due to high EGR and low NOx combustion, it is necessary to consider further increasing the injection pressure as a black smoke countermeasure when the O2 concentration in the intake air is greatly reduced.On the other hand, the combination of fuel injection system and after-treatment technology is also very important.

one. What are the conditions for generator sets to operate side by side? The entire process of putting generator sets into parallel operation is called parallelism. Run one generator set first and send the voltage to the busbar. After the other generator set is started, it is parallel to the previous generator set. At the moment of closing, the generator set should not experience harmful impact current and the shaft should not be hit suddenly. After closing, the rotor should be pulled into synchronization quickly.

The current diesel generator industry is such that investing in diesel generator fields will result in no return or even loss of money. However, some people still invest, and there is a huge demand for diesel generator equipment.Where opportunities exist in the market, competition exists where opportunities exist. Where competition exists, there is no way to escape the natural law of 'big waves wash away the sand, and the survival of the fittest'.Currently, 1/3 of the wind turbines are basking in the sun because the grid connection problem has not been solved.The entry barrier for the fan manufacturing industry is low, and 80% of the more than 70 complete machine manufacturing companies are simple assembly plants.Blades, generators, gearboxes, etc. are purchased from upstream parts companies, assembled and sold in various specifications, causing difficulties in grid connection.A few months ago, a new fan installed by a fan manufacturing company fell from the air and was damaged.It’s time for the market, which is a mixed bag of good and bad, to be cleaned up.Policies are becoming more and more standardized, the need for the introduction of standards is becoming more and more urgent, and competition is becoming more and more fierce. After the golden years of explosive growth, diesel in the post-'golden era'

The power shortage and frequent pull-out limiting electrodes have greatly affected people's lives and industrial production, and have also caused diesel tension in Zhejiang, Jiangsu and other regions to be tight and even partially out of stock, because the company's own diesel generator sets consume a large amount of diesel. This year's power shortage has arrived unexpectedly. According to data, except for Heilongjiang, Jilin, Liaoning and Xinjiang, other regions across the country have experienced power cut-offs to varying degrees. Similarly, Zhejiang, Jiangsu, Shanghai, Guangdong and other places are still the best. In view of the lessons learned last year, more companies, especially foreign trade processing companies, have to purchase diesel generator sets to deal with the panic in order to complete foreign orders on time and deliver goods in a timely manner. Some diesel generator manufacturers have launched 'out of stock' signs, and the large demand has brought some diesel engine manufacturers that were originally 'in desperate situations' back to life. The price of diesel generator sets is also high, with the price of 200KW diesel generators rising from 120,000 to 130,000 yuan to 200,000 yuan.

The Development of China's Ultra-Large Displacement Diesel Engines my country's automotive diesel engine market has gone through several important time points from the quasi-heavy-duty stage to the super-heavy-duty stage of more than 10L.Among them: 2003 was the period of intensive launch of quasi-heavy-duty diesel engines, and the displacement was concentrated at 7L; 2005 was the first stage of heavy-duty diesel engines, and the displacement was concentrated at more than 8L; 2006 was the second stage of heavy-duty diesel engines, and the displacement was between 9 and 10L ; From the second half of 2008 to the present, major manufacturers have begun to focus on the launch or mass production of diesel engines above 10L, and vehicle diesel engines have entered a period of super heavy-duty and large displacement above 10L.The characteristic of this period is that it is based on 11L and aims at the next displacement range-12~13L.The current situation of supporting extra-large displacement diesel engines and complete vehicles. Since 2008, some new 12L and 13L extra-large displacement diesel engines have been launched by various diesel engine factories one after another, thus making my country's extra-large displacement heavy-duty engines above 10L

Since its establishment, Haixing Company has gradually developed into a new modern private enterprise in Taizhou City from three aspects: technological research and development of generator sets, expansion of generator set production scale, and improvement of generator set-related services. The 'Haixing' brand diesel generator sets produced are widely used in ships, petrochemicals, highways, railways, water conservancy hubs, municipal engineering, postal and telecommunications, industrial and mining enterprises, hotels and other fields.

Because there is no ignition system, the fault is low (3), reliable operation and durability. Because there is no ignition system, the fault is low (4), the harmful emissions are low (5), and the fire safety is safe

1. Structure The basic structure of a diesel generator set is composed of a diesel engine and a generator, and the diesel engine acts as a power to drive the generator to generate electricity. Let’s first talk about the basic structure of a diesel engine: it consists of components such as cylinders, pistons, cylinder heads, intake valves, exhaust valves, piston pins, connecting rods, crankshafts, bearings and flywheels. The diesel engine of a diesel generator is generally a single-cylinder or multi-cylinder four-stroke diesel engine. Let’s talk about the basic working principle of a single-cylinder four-stroke diesel engine: the diesel engine starts by rotating the diesel engine crankshaft through manpower or other power to make the piston reciprocate up and down in the airtight cylinder on the top. The piston completes four strokes during movement: intake stroke, compression stroke, combustion and work (expansion) stroke and exhaust stroke. When the piston moves from top to bottom, the intake valve opens, and the fresh air filtered through the air filter enters the cylinder to complete the intake stroke. The piston moves from bottom to top, the inlet and exhaust valves are closed, the air is compressed, the temperature and pressure increase, completing the compression process. live

A diesel generator set refers to a power machine that uses diesel as fuel and uses diesel engine as prime mover to drive the generator to generate electricity. The diesel engine converts the heat energy released by diesel combustion into kinetic energy, and the generator converts the kinetic energy into electric energy! However, during each conversion, part of the energy will be lost! The converted energy is always just a part of the total energy emitted by combustion, and its percentage is called the thermal efficiency of the diesel engine. In order to describe thermal efficiency practically, diesel generator manufacturers often use the G/KW.H parameter, which means how many grams of oil consumed in one kilowatt per hour. If you replace this unit with liters, you will immediately know how many liters of oil you consume, so that you can also know how much money you spend in an hour. Some manufacturers directly tell L/H, which means how many liters of oil consumed in an hour. Methods for calculating fuel consumption: 1. Generally, high-horsepower diesel engines with a maximum capacity of more than 100 horsepower must be consumed per horsepower hour when running at full load.

The concerns about whether the generator set is operating normally. Haixing generator set technicians remind you that there are several points that need to be paid attention to at all times: 1. AC ammeter: The needle indicates whether the indicator is normal, switch the current switch, measure the phase current value between each phase sequence. It is best not to exceed 10%. 2. AC voltage meter: Is the voltage indicated by the meter pin normal? 3. Whether the oil pressure indicated by the oil pressure gauge is within the normal range. 4. Charging meter: Whether the pointer is in the direction of (+). 5. Whether the water temperature indicated by the water temperature meter is within the normal range of 65℃~93℃. 6. Tachometer: Is the engine's rotation number appropriate? (1800 rpm at 60Hz) 7. Whether there is any abnormal sound or vibration of the generator engine.
